JACK.

Application leu'l February la; 1922. Serial No. 533,635.

To all whom it may-Gomera.' Y

Be it known thatI, Fenu DEAL a citiz en of the United-States, residing at ton, in the county of Uumberland and State 155 ci lNew Jersey, have invented new and useful Improvements in Jacks, of which the following is a specification.

.'.lhe present' invention relates to apparaw tus for elevating the axle oi a vehicle so that a wheel thereon may swing tree of the ground.

VObjects of the invention are simplicity and durability of construction.

Anotherobject ot the invention is to produce a device which may be readily transported from place to place and which may be stored in comparatively little space with-I in the vehicle in connection with'which it is tohe used. ao Another object of the invention is to produce a device which will cooperatel with the power of a vehicle in raising the axle., as above set forth, without the necessity oi' the operator gettingunder the machine or utting forth anyhuman exertion in raising the' wheel trom the ground.

Another object isto produce a device free otfdelicate and breakable parts and which will support the axle in stable equilibrium.

lligfl is aside' view of a jack built in accordance with my invention;

Fig. 2 is a view of the jack looking at the same fromfthe left as shown in Fig. 1;

Fig. 9 shows the position et the jack when the axle is supported thereon; and

Fig. 10 shows the position of the block and operating lever in relation to the jaclr when the wheel is being dismounted from the jaclr.

Referring to the drawings in detail by reference characters', l5V designates a base withwhich may be integrally formed an upright 16, the upright he preferably inclined at an angle to the base member and, the inclination being forwardly or toward the vehicle when the jack is eet up for use, the purpose of which will later appear.

ln order to adapt the jack for axles ot various heights from 'the ground, the upright 16 is provided on its sides with parallel longitudinally extending grooves 17 and an arm 18 adapted to receive an axle ot the vehicle which is provided with tongues 19 slidable in said grooves. Apertures. 20 in the upright and a cooperating pin 21 are also provided to secure the arm in various ad'usted positions on said upright.

e upright 16 is provided intermediate of its ends with a leg 22 extending rear wardly and downwardly at an angle, the

urpose of which will presently appear.

he leg may be provided with a base 23 formed on the end thereof and corresponding' with the base 15.

ln operation, alter the axle of the vehicle has been brought into position on the arm 18, the jack is rocked rearwardly by the movement of the vehicle elevating the axle and raising the adjacent wheel off the aground. The rearward movement of the jack continues until the base 23 of the leg 22 contacts with the ground when further rearward movement is arrested. The wheel is elevated when the jack is rocked rearwardly because the relation of the upright and the leg are such that the distance from arm 18 to anv point on the line betweenthe bases of the leg and upright is greater than the distance from the arm to the base 15.

'lll

In order to facilitate the rearwardly rockment, the weight of the load rests on the rounded portion 24 of the base 15 and on the rear edgel of base 23, in this manner distributing the load between the leg and upri lit.

gI`he jack may be used without accessories by adjusting the arm 18 to such a height that the axle of the vehicle may b e brought into position on the arm 18 by simply baclting the vehicle along the ground with the Jack properly positioned to receive the axle on the arm and the tiltin of the Jack alone, as set forth above, may e utilized toelevate the axle. Should it be desired, however, to elevate the axle to a. greater height than is possible in this manner, the arm 18 may be adjusted on the upright to a desired height and an accessory used to give the axle an initial elevation to bring it to a level to pass freely onto the arm.

Such an accessory is provided in the form of a block 25, formed with a base 26, a flat top portion 27, an inclined front portion .28, and an abrupt perpendicular rear portion 29 and for running the vehicle on to the ]ack, the said block is placed rearwardly of the wheel (see Fig. 8) with the inclined portion 28 toward the wheel and in position for the wheel to run up said incline. The ]ack is at the same time placed in such relation to the vblock that as the wheel passes up the 1 nn clined portion 28 of the block, the axle will be moved to position above the arm 18, and as the wheel passes over the flat portion 27 the jack will be tilted rearwardly, raising the arm into contact with the axle, in this manner preventing a sudden sharp drop of the axle onto the said arm.

The block may also be used to dismount the axle from the jack and in order to adapt it for this purpose, a foot lever 30 may be provided comprising an arm 31 having a pedal 32 at one end and a side extension 33 at the other. The pedal and the extension lying at right angles to the arm 31 and extending in opposite directions therefrom. The extension 33 is attened so as to adapt it to be slid under the base of the block and to afford leverage in tilting the block when the lever is depressed from the position shown in Fig. 6 to that shown in Fig. 10.

To prevent wear of the block and to prevent the lever from biting into the ground and rendering itsl turning movement ineffective, a metallic plate 34 is secured to the underside of the block and part way up the rear side, where it is rebent upon itself at 35 and is brought back in parallelism to itself under the block in the form of a tongue 36, hinged at one end, namely on the line 35.

To remove the axle from the jack, `the block is placed beneath the wheel with the inclined portion extending rearwardly, (see Fig. 10), vthefoot lever is then depressed to position as shown, elevating the' inclined portion to ppsition to give the wheel traction to run olf t e jack.

It will bevnoted from the above description, that I have produced a device for raising a vehicle wheel oif the ground and to lower it again; withoutv any considerable manualexertion and without the necessity of getting under the vehicle; one which ma be readil transported from place to place wl ich may ge used under varied circumstances; which has few parts to get out of order or break and which may be used on front or rear axles; which is simple of construction, easily manufactured and'which alfords a firm, stable, strong support for the axle when mounted thereon. I claimz- 1.
